Dial Torque Wrench

  • Wide range and high accuracy dial indicating torque wrench. Ideal for torque quality inspections
  • Easy to ready dial face has follower hand memory pointer that stays on peak torque for convenient reference
  • Use for tightening purposes by simply rotating the dial to the desired torque. Completed tightening is achieved when the pointer indicates “0”.
  • DB is not length dependent. Therefore, accuracy is consistent regardless of where the hand is placed during operation.
  • The dial indicator has a full-surround protective cover to prevent damage to external objects (except DB420N, DBE, and DBR series models).
  • DB25N to DB280N models have a resin grip. Lowest torque range models have index finger handles designed to guide you to use light hand force to avoid possible over-torque.
